This is a Spenserian stanza written about recent research, which found that Planet 9, a planet which resides within our own solar system, may in fact be an exoplanet, i.e. a planet which orbits a star other than our Sun. It is thought that our Sun, in its youth (approximately 4.5 billion years ago) stole Planet 9 from the orbit of its original star. At the moment it is unsure what Planet 9 looks like, but it is believed to be approximately ten times the mass of our Earth. This research challenges the very definition of an exoplanet, and realistically opens up the possibility of being able to send a space probe to investigate a planet that began its life outside of our solar system.
